WELT TEMPERING MACHINE Application filed September 21, 1927. Serial No.221,056.

This invention relates to machines and processes for preparing weltingfor the inseaming operation and more particularlyto a novel machine andprocess especially adapted for handling and properly tempering weltingjust prior to its being drawn through the Welt guide of the inseamsewing mach ne, but it will be understood from the following descriptionthat the machine may be used in combination with, or auxiliary to, otherkinds of machines for operating on welting, or it may be used whollyindependently of any other machine; For the purpose of defining thenovel features and advantages of the present invention, Goodyear weltingwill be referred to generally hereinafter, but thosev skilled in the artwill recognize that the invention is not limited to tempering only thistype of weltlng.

VVelting of all kinds may come to the shoe manufacturer from the weltingmanufacturer in one of two forms according to the manufacturers needs.The majority of shoe manufacturers desire that the welting be delivered2 to them in hanks while the remainder desire that it be wound on aspool. The present invention will handle equally well both hanked orreeled welting and will temper either perfectly withoutchange in thedevices which direct the welting through the water.

Prior to the present invention many attempts have been made to design amachine for wetting or moistening welting in a manner to insure thatonly the portion of the welting thatis to receive the inseam stitcheswill be so tempered as to insure a tight inseam when presented to thestitch-forming mechanism of the inseam sewing machine. These haveincluded a machine having provision for delivering water through" anozzle into the stitch-anchoring groove in the flesh Side of thewelting; another having provision for quickly. drawing the weltingonedge be-j tween side guides, rising above the water level,

in a tank of water with its beveled edge immersed to at least the vdepthof the groove; and a third having provisionfor wetting onlythe flesh,side of'the welting. The aim and purpose of these various attempts atperfec-v tion inwelt tempering has beento prevent the welting from beingwet too much or too long by the water and particularly to preventWetting the grain surface of the welting that is to be exposed ontheshoe. Success has not crowned these inventions as none are incommercial use today and shoe manufacturers have, up to the introductionto then of the machine of this invention, been forced to continue to usethe crudest and earliest known method of tempering welting, namely,-dipping the entire blank in water and then waiting for it to dry outenough to insure sewing a tight inseam. v V When the process of dippingthe hank to temper the welting first came into use the leather used forwelting was prepared in quite a different manner than it is today. Thetanning processes were such that the hard leather needed, before sewing,to be soaked and then to dry and mull under cover until it became softand. cheesy thus insuring a tight inseam but, at the same time,developing many disadvantages. Today the leather for welting is curriedbefore it is stripped into fillets and is, therefore, quite mellow afterthe cutting operation to produce the grooved and beveled strand. Suchwelting does not need to be soaked and then mulled. Its tann'age is suchthat the only necessary treatment is a moistening of the inner marginthat is to receive the inseam stitches. And yet, because no satisfactoryprocess for merely moistening has heretofore been developed, the weltingof to-' day is treated prior to sewing just as it was when soaking wasessentiaL:

' Many disadvantages flow from submersion of the hank in water. Ifsoaked too long the welting, particularly narrow and thin wommuch itbecomes brittle and weak in the fibre, particularly on the grain side,which interferes with the inseaming and welt beating operations andpromotes cripples. Unless a hank, tempered. by submersion, V is entirelyused at the end of a days stint then the unused remainder may become sohard and brittle by the next day that it requires: re-temering with theattendant disadvantages. Veltin-g today is made from high grade leatherwhich is so tanned that it is meant to be wet only once and then harden,where water has been applied, while on the shoe. A second all overwetting will cause it to shrink in width and become harder. Aside from aloss of shape, which is particularly disadvantageous becausemanufacturers watch the Width of welting (extension on the shoe) down toof an inch and further, the hard welt is more difficult to sew andoperate on later. Velting leather is always stretched before cuttinginto fillets and it is the later shrinking after tempering which hardensit and tightens the inseam.

From the foregoing it is obvious that welt tempering is a delicate andhighly important operation the main requirement of which has alwaysbeen, but not attained up to the time of this invention, to wet ortemper only just enough of the inner margin of the welting to enable theinseam sewing machine to sew a tight seam, and at the same time be surethat no water seeps over, or in any way is drawn toward or impingesupon, the grain surface that is to be exposed on the shoe. Thus all thedisadvantages hereinbefore recited are wholly eliminated. A furtheradvantage of correct welt tempering comes from the ability toimmediately sew .and beatout the sewed Welt, whereas with weltingtempered :by submersion there must be a drying period of several hoursbetween successive operations.

The object of the present invention is to provide a process of temperingwelting, and

a machine for carrying out the process, that will invariably wet ormoisten only that much of the grooved margin of the welting as isrequired for sewing a tight inseam, and no more. The various novelfeatures of the machine through which this is made certain will beascertained from the following clescription.

To the accomplishment of this object and such others as may herein-afterappear, as will readily be understood by those skilled in the art, theinvention comprises the features and combinations of parts hereinafterdescribed and then particularly pointed out in the app ended claims.

The features and scope of the invention will best be understood from adescription of the preferred embodiments thereof illustraed in theaccompanying drawings, in which:

In this figure the circular dotted line represents the columnof an inseam sewing machine such, for example, as is disclosed inLetters Patent of the United States to Andrew Eppler No. 1,076,878,dated October 28, 1913;

Fig. 6 is a view, in rear elevation, of the means at the forward end ofthe tank for directing the strand to the welt carrier;

Fig. 10 is a view, in longitudinal section, of the tank with weltingbeing directed therethrough by the modified welt carrier.

In the embodiment of the invention illustrated by F 1, 2, 3 and 5 of thedrawings I show what I term a universal welt carrier indicated generallyby 10, so constructed as to be adjustable to receive many differentsizes of welting within certain limits. The guide 10 is suspended abovea water tank 12 from a cross-bracket 14 which is adjustable verticallyon guide pins 13 and 15 secured at each side of the tank 12.

The water in the tank 12 is maintained at a constant level by means ofan intermittent feed, from the supply contained in a bottle or-othercontainer 16 (see Fig. 9), induced by evaporation from the tank underthe wellknown barometric principle. The contents of the bottle is sealedto the atmosphere, by reason of its air-tight support in the bottleholding mouth 17 (Figs. 5 and 9), and evacuation to the tank 12 canoccur only when the water level in the tank is lowered sufliciently touncover the upper end of a water gate 18. This water gate has aninverted V shape (as indicated by dotted lines Fig. 5) so that thereplenishing is in such small quantities as not to disturb the calm ofthe water in the tank 12.

The adjustable guide bracket 13 provides for setting the welt guide 10to a predetermined depth in the water of the tank, to accommodate anysize or style of welting held by the carrier, i. e. in order to obtainthe same (Fig. 5). .Dependingfromtthe collar:24'

is a tubular extension 23 preferably integral with thecollar and ,in-anyevent adjustable vertically on the pin 13 with the collar. This tube 23forms a slide bearing, for thebracket sleeve20. A crank arm 26, having ahandle 28, is pivotally mounted on the collar-"and-a;

1 vertical, pivoted link connects the sleeve 20 tothe crank arm. Thecrank arm' and link form a toggle with itsknuckle; at '29 and-a stop pin31 on the collar serves to maintain the togglestraight when thehandle28is moved to the left, as shown byFig. 1. When the toggle is straight, orextended, the welt carriersupport 14 isat its lowest position determinedby the setting of the collar 24. By loosening the set screw 25 thesupport 14and its depending welt carrier 10 may be moved together, dueto the toggle connection, toward or from the water'leveluntilthedesiredsettingis attained.- It may be desirable, at times, 7

to wholly remove the carrier and support from the pins 13 and 15. Inorder to preserve the setting attained by theprevious adjustment, andeliminate re-adjustment when the parts are replaced, thelower end of thepin 13 may be threaded and provided with a nut32 (Fig. 1) to be screwedagainst the lower-end of. the tube 23 afteran adjustment has beenperfected and then held in POSiillQll;

by, a lock-nut 33 or other suitable securing means. The nut'32 thusfunctions as afixed,

stop to determine the verticalposition of the welt carrier with respectto the water level.

The universal welt carrier;,10 has three parts; a body member 34hayingextending pins 36 and 38 set at right angles to each other,

a side-guide member 40 slidable on the pin 36, and an end-guide member42 slidable on the pin 38. The adjustable members 40 and 42 are held atany desired position on their pins by set screws 41 and 43 respectively.The side-guide member 40 is constrained to move longitudinally,; withoutrotation,; on its pin 36 by a face bearing 44 between it and the bodymember. The end-guide member 42 is constrained to move on its pin 38 ina likemanner by a .slide bearing comprised of a.

fork 45 whichembraces the reduced end of a lateral leg 46 of theside-guide member. The, forked bearing serves to maintain the end andside members in the same plane under all conditions of adjustment andthe face bearing co-operates therewith; to maintain the end-:and sidememberscin the plane of. the

body member, It is obvious from a studyof Figs; 1 and 2 how the sizeof.the :0pening; or.

guideeye-formedby the'three membersof the.

welt carrier maybe altered to. accurately'engageand directthrough thewater tank differentgwidthsiror thicknesses of welting.

It is of the utmost importance that the weltinggdrawnthro'ugh the weltcarrier, and thusithrough the water,,'be so held that only itsgrooved:-margin will be moistened. In-' suranceimustbe had that theportion of the grainwhichis to be BXPOSGClOIl the shoe is protectedrfromimmersion; To this end pro-T visionis; made: for setting the weltcarrier in such QIPOSltlOIl that the welting, while in the guide 'eye,stands oblique to the water level with I its .grain side uppermost andits grooved ;margin tipped downward for immersicnras'theweltingis drawnacross the tank 12:. ,g This angular adjustment of the welt carrierissecured by making a head 48 onthe. body memb,er;34,slidablein acu'rvedway 50. (see.,Fig.-'t3) fOI'lYlGCllOl'l the carrier support 14.The carrier l'Qjs held :in any desired position along its support 14 by.a lock screw 49....

.lwill now describe afeature of my welt carrier that I :deem to beessential in that it functions to maintain the grain surface to beexposed on the-shoeperfectly dry through out the tempering operation..It will be 010-.

served :(Fi s. 1 and 2) that the lowerend of thebod'y member 34 of thecarrier is cut away at 52, preferably but not -necessarily,.a semi-'circular, cavity,;.the;lower corner 54 of-which bears on thek weltingeither directly at, or if desired just beyond, the grain corner formedby cutting. the'welt: bevel, or oppositethe groove in the flesh side.The are of the curved way, 50 is struck from this corner54 asav centerand all angular movement of, the welting. relative 'to .the water leveltakes place about this fixedtcentenof adjustment. The

preliminary vertical adjustment of the welt carrierIO isisuch that thecorner 54 stands at,; or possiblyjust above, the waterlevel, hencenomatter. howmuch theangle is decreased between the flesh sideof thewelting.

'andwater level, in order towet more of the flesh side, the grain sideof the welting will never be immersed beyond the line of pressure of thecorner 54.: Furthermore the cavity; 52- provides a shoulder rising fromthe grain functioning to prevent water being drawn by, capillaryattraction beneath the I grain side wall of the guide-eye and thence onto that, portion of the grain to be exposed on the shoe. Moisturewillnot seep upward beyond the corner 54 but'it will do so if the grain sidewall of the guide eye is made as a contmuous surface similar to theflesh side wall formed by the leg 46. The flesh side lee ward and fromthe fixed point 54 on that member thus preserving the grain side depthof immersion for all sizes of welting for which the carriermay beadjusted.

The machine is set at a convenient height upon a bench or table and thewelting to be tempered comes from a hank .or reel at a lower level,passing upward over a directing bar 56 (Fig. 6) having an upperprotecting pin 58, on the forward edge of the tank 12. The surface ofthe bar 56 slants relatively to the water level, the obliquityapproximating that. of the guide eye of the welt carrier to relievestrain on the guide eye. As best shown by Fig. 2 the ends of the guideeye may be provided with rounded abutments 59 to further assist thewelting in an easy passage through the welt carrier. After immersion thewelting passes beneath a guide roll 60 which is freely rotatable on apin 61 held at each end in brackets 62 (Fig. 5) that are angularlyadjustable in ears on the tank walls to enable the guide roll to be setin the best position for lifting the welting out of the waterimmediately it has passed beyond the welt carrier. From the roll 60 themoistened welting passes upward (see Fig. 3) conveniently to themeasuring roller 64 of the inseam sewing machine. This roller isprovided with clamping mechanism for holding the welting after the weltcutting operation is performed on completing the sewing of a shoe.

The general location of the roller .64 is indicated by dotted lines inFig. 5 and this figure shows also how the machine of the pres entinvention may be mounted on a rear corner of the sewing machine worktable. The work table 65 has a bounding lip or rib 66 from which is hunga base plate 68 for supporting the tempering machine. The base plate hastwo holes 69 at one end which, when the plate is situated diagonallybeneath the table 65 (see Fig. 5), are just outside the rib 66 and thisend of the base plate may thus be clamped to the table by U-bolts 70which pass upward and hook over the rib. The other end of the base plateis provided with two spaced posts 72 (see also Fig. '9) having reducedends forming shoulders on which rest collars 73 at the ends of arms 74extending laterally from the tank 12. The machine is removable at willfrom the posts 72 for dismantling, inspection or repair.

From the measuring roller 6% the welting goes to the welt guide of thesewing machine and from thence to the work-feeding and stitch-formingmechanisms. Between the two rolls 60 and 64 the welting is turned overso as to lie flesh side up as it passes to the sewing machine weltguide, in proper position to be stitched to the shoe. This twist in thewelting does not interfere with .the advance of the tempered welting bythe workfeeding mechanism because there is about a 1, see; 9 e0 pletingthe operation on a shoe, the operation of the clamp on the roller 64holds taut the length of welting between the measuring roller and theroll 60 and prevents the por-' tion between the roll 60 and theweltcarrier 10 (see Fig. 3) from dropping downward into the water. Ifthere is any slack the weight of the substantially vertical run willcause it to sag downwardoutside the tank and thus straighten the portioninside the tank and hold it above the water level.

At night, after the days work is over, it is not necessary to unthreadthe welting still unused from the guide eye of the carrier 10. By movingthe handle 28 (Fig. 1) to the right the toggle 2630 is broken and thesupport 14 with its welt carrier is lifted on the tube 23 to a positionwhere the welting is above the water level. A contractile spring 75connected to pins on the sleeve 20 and fixed collar 24: prevents theguide '10 from sliding down again due to its own weight. In consequencethe unused welting, not being left overnight in a soaked condition aswas the practice prior to this invention, is in prime condition fortempering and stitching when the sewing machine operator starts the nextmorning. 7

In the modified form of the invention shown in Figs. 7, 8 and 9 the tank12 and its water supply and support, the forward bar 56 and the rearroll 60,'and in general the adjusting mechanism for setting the weltcarrier as a whole for correct immersion of the grooved margin of thewelting are all unchanged. In Fig. 7 the dot and dash lines show theraised position of the welt carrier after the handle 28 has been movedand the toggle 2630 broken as has hereinbefore been described.

The construction of the welt carrierconstitutes the principalmodifications. The modified welt carrier comprises a disk having aplurality of guide eyes of different sizes for accommodating differentsizes of welting. This disk 80 is mounted in a split? ring portion 82depending from the welt carrier cross-bracket 84. The disk has a flangedforward edge (see Fig. 10) and form. Each cavity 86 in the grain sidewall has the same abrupt grain side engaging corner'54, as hereinbeforedescribed, to prevent wetting of the grain by capillary at tractionbetween. the wall-and welting,- and any one of these several guide eyes,when in in operative position as shown by Fig. 7 serves the same endasdoesthe adjustable guide-eye of "the preferred" form; Each guide-eyeopens through the peripheraledge of the disk 80 thus permitting the diskto be applied to welting already threaded through the machine (see Fig.8). There may be heavy places in the hank and while the fit should beclose yet the welting should travel freely through the welt carrier. r

In Figs. 3 and 4: there is shown a device, applicable to either form of'the invention, for taking all kinks out ofthe welting before passingover the directing bar 56. Kinks are very apt to form in weltingdrawn-from a hank and this is one advantage of using reeled welting. Abracket '90 projects forwardly from the front wall ofthe tank andcarries a loosely rotatable directing roll 92 set slightly oblique tothe horizontal-inconformance with the obliquity of the directing bar56.- Depending from the bracket 90 are two bars9 having inwardly turnedends (Fig. 4;) about which-is clamped. a mouth formed of two pieces5360f generally triangular form, the pointed ends being directeddownward toward the hank of welting.,- The mouth piecesconstitute aguide-for thewelt andihave smooth opposed facesispaced'apart a distanceto accommodate the thickest 'welting that may be used. Thepointedendsarerounded, forming together a'nose about which? a guard in the formof aring 98 is soldered. If the welting becomes twisted (see- Fig. passagethrough the guide formed by the two pieces '96 will cause it to untwist:This untwisting'may develope a kink (see Fig. 4 in which event the edgeof the "kinked welting rides against the under surface'of the v guard 98and eventually is thrown back after the twisted portion has been fedthrough. A device of this nature is quite necessary in feeding to themachine from hanks. In setting up the machine it may be found that thebench,'or other support, is' not level in which event the water levelwill not be parallel to theupper plane of the tank as illustrated byFigs; 1 and '9,jshowin'g the ideal" condition. Under such conditions thewelt carrier is first adjusted both'vertically and angularly, ashereinbefore described, to as perfect a position aspossibleandth'en the"water level is changethf'is found necessary to prevent wetting more thanthe grooved margin of the welting, by the water level adjustmentshownyin Fig. 9f The month 1-7 for receiving the bottle neckf-isprovided with avertically adjustable bottle neck-hold-' er 100 held inanyd'esiredpositionby set screws or other suitable'se'curingmeans; By
